标签: html css twitter-bootstrap navbar

我使用bootstrap并尝试将搜索表单放在导航栏下拉菜单中,但我发现表单看起来被压扁了,因为下拉列表的宽度太小。此外,表单元素不是我想要的。我该如何解决这个问题?

我一般都是CSS和网页设计的新手。请帮忙!

试试这个:

.navbar-nav>li>.dropdown-menu { width: yourwidth }

您可以添加display: inline-block,使其宽度自动根据其内容

您可以在dropdown.less

中增加“min-width”值

或在css中新建一行

.dropdown-menu { min-width: 200px }
